Seals, sea lions, and walruses (oh my!) are widespread, successful, and invariably charming. In this episode, we take a look at how they’re adapted for their aquatic lifestyles and how they might have gotten that way. We’ll explore some of the unanswered questions about their origins and evolution, and we’ll take a tour through their diverse but spotty fossil record.
